Hi, I'm considering buying a new 13' MBP. Following the process outlined here I'd replace the optical drive with a ssd: http://lifehacker.com/5541774/how-to-install-a-solid+state-drive-in-your-macbook Basically, I wanted to take advantage of the SSD for bootup and apps, by installing a 40GB Intel X25 . The cost of both the SSD and the casing I would have to put it in to replace the optical drive would come out to a little over 200. I would obviously use the HDD for storing all my files. What I'm asking is if: a) you guys think this is a good idea. b)if I were to do this would 40GB be too small for the OS and programs c) would the warranty/ appcare be voided? edit: d) Am I better off just spending $225 on apple's ssd and keeping my optical drive Thanks!
